Esp getting into hanging state after 1-3 days neither sending or receiving data. #17

First of all thanks for the great work on this, works flawlessly with a small but. My ESP hangs every 1,2,3 days and I need o shut down the unit and enable it back again to restore readings and control. I got the power supplied from the recu, my friend has a separate power via phone charger and it works for him without any issues. Any ideas what may be causing the issues in my case?

Hey, you're not the first one to tell me such issue. Unfortunately my esp32 is running stable since months now. Not a single time I had to powercycle it.

What board are you using? How distant is the WiFi AP from the ESP32?

I'm using ESP-WROOM-32 Distance between AP - ESP ca 7-8m through two walls, signal readings on the router = Medium but okay I have another ESP for voltage/current readings which is bit furhter away and works without issues. I would remove the wifi signal from the equation. What I haven't done and what I will check next time when it happens is whether the ESP is responding to pings while in hang state. I wonder if a periodic restart on ESP (for example at midnight) would help, but still wouldn't know what piece of code should be added and where.

Interestingly since I posted this issue the ESP didn't crash so far :)
